Emergency warning light

Claim 2

An emergency signal light comprising a base adapted to be mounted atop an emergency vehicle and having lamp means positioned thereabove, a generally transparent plastic dome mounted on said base and enclosing said lamp means, said dome having a generally circular sidewall integral with a top wall, a plurality of circumferentially spaced vertically extending rib means integral with said sidewall on the interior of said dome and adapted to support light beam modifying placards, and means on said base for mounting said base atop an emergency vehicle in non-rotatable fashion.

Claim 3

The structure of claim 1 in which said base is essentially cup-shaped having an arcuate sidewall integral with a bottom wall, a plurality of integral supports upstanding from said bottom wall within said cup-shape to provide support for said lamp means.

Claim 4

The structure of claim 1 in which said base is generally cup-shaped having an arcuate sidewall and circumferentially spaced apart integral flanges projecting outwardly from the upper sidewall, said flanges being equipped with detent means, and a retainer ring equipped with detent-fitting projections mounted on said base in engagement with said dome and said flanges.

Claim 5

An emergency signal light comprising a base adapted to be mounted atop an emergency vehicle and having lamp means positioned thereabove, a generally transparent plastic dome on said base and enclosing said lamp means, and a retainer ring releasably clamping said dome and base together, said dome being mounted on said base and having a perimetric flange, said base having a plurality of outwardly facing detent-equipped ramps adjacent the top thereof, said retainer ring being constructed and arranged to cooperate with said ramp detents in releasably clamping said dome to said base, said dome being equipped on the interior thereof with a plurality of perimetrically spaced apart means for mounting color filter means.

Claim 6

An emergency signal light comprising a base adapted to be mounted atop an emergency vehicle and having lamp means positioned thereabove, a generally transparent plastic dome on said base and enclosing said lamp means, and a retainer ring releasably clamping said dome and base together, said dome being mounted on said base and having a perimetric flange, said base having a plurality of outwardly facing detent-equipped ramps adjacent the top thereof, said retainer ring being constructed and arranged to cooperate with said ramp detents in releasably clamping said dome to said base, said dome being equipped on the interior thereof with a plurality of perimetrically spaced apart means for mounting color filter means.

Claim 7

An emergency signal light comprising a base adapted to be mounted atop an emergency vehicle and having lamp means positioned thereabove, a generally transparent plastic dome mounted on said base and enclosing said lamp means, said dome having a generally circular sidewall integral with a top wall, said dome being equipped on the interior thereof with a plurality of perimetrically spaced apart means for mounting color filter means, and means on said base for mounting said base atop an emergency vehicle in non-rotatable fashion.

Claim 8

An emergency signal light comprising a base adapted to be mounted atop an emergency vehicle and having lamp means positioned thereabove, a generally transparent plastic dome mounted on said base and enclosing said lamp means, said dome having a generally circular sidewall integral with a top wall, said dome being equipped on the interior thereof with a plurality of perimetrically spaced apart means for mounting color filter means, and means on said base for mounting said base atop an emergency vehicle in non-rotatable fashion.

Claim 9

An emergency signal light comprising a base adapted to be mounted atop an emergency vehicle and having lamp means positioned thereabove, a generally transparent plastic dome mounted on said base and enclosing said lamp means, said dome having a generally circular sidewall integral with a top wall, and a plurality of circumferentially spaced vertically extending rib means integral with said side wall on the interior of said dome and adapted to support light beam modifying colored films, each rib means having a width substantially less than the width of the film, said dome being formed of substantially clear plastic whereby light from said lamp means passes through relatively wide colored films and relatively narrow strips of substantially clear plastic, and means on said base for mounting said base atop an emergency vehicle in non rotatable fashion.

Claim 10

An emergency signal light comprising a base adapted to be mounted atop an emergency vehicle and having lamp means positioned thereabove, a generally transparent plastic dome mounted on said base and enclosing said lamp means, said dome having a generally circular sidewall integral with a top wall, and a plurality of circumferentially spaced vertically extending rib means integral with said side wall on the interior of said dome and adapted to support light beam modifying colored films, each rib means having a width substantially less than the width of the film, said dome being formed of substantially clear plastic whereby light from said lamp means passes through relatively wide colored films and relatively narrow strips of substantially clear plastic, and means on said base for mounting said base atop an emergency vehicle in non rotatable fashion.
